Customer story: The Swedish shipbuilding company Aerodyn increases depth of cut by 50 %, thus doubling tool life

CERATIZIT S. A., Mamer, Luxembourg (headquarters), March 2008.

The Swedish company Aerodyn specialises in the machining of blades for propelling screws. The cast skin is eliminated and the profile finished through milling. After milling the surfaces are carefully polished. In this way, since the year 2000, several projects have been realized in close cooperation with the carbide expert CERATIZIT and productivity increased.

Propelling screw in application
The propelling screw converts the energy produced by the motor into motion. The propeller blades are characterised by a hydrodynamic wing profile. The blades are designed in such a way that the water streams around them asymmetrically when they rotate. A difference of pressure is caused in or contrary to the direction of movement. A current called 'thrust' is generated and drives the vessel.
